Zigbee control light
Smart home devices have exploded in the past few years. What used to be called "home automation," and is still called "the Internet of things," has moved into a friendlier category we call the smart home. ZigBee is based on IEEE 802.15.4 personal LAN standard. You just need to know that ZigBee is a specification that's been around for more than a decade and is widely considered an alternative to wi-fi and bluetooth for some applications, including low-power devices that don't require much bandwidth -- like smart home sensors. A typical example is when you have an adjustable zigzag light bulb and an adjustable zigzag light switch, and you want the light switch to control the bulb. With Zigbee control, the two devices -- even if they come from different manufacturers -- speak the same language, so there are no communication barriers.
